BIG-IP LTM Front ending Horizon View UAG appliances

Does anyone have any experience load balancing VMWare UAG appliances, using LTM? I have created a vip with multiple service ports (443,8443,4172 both TCP and UDP), written a persistence profile with source address affinity and 'match all services' selected in the profile. If one UAG appliance is up behavior is correct and the client logs in and is presented with a desktop. If both appliances are up heath check passes however the client receives a black screen and disconnects. This is for View 7.1 unfortunately the iApp that exists for 6.x is not backward compatible with 7.1.
